one way and two way slabs in structural analysis

One Way Slab V/S Two Way Slab – Structure Analysis

Posted by

The comparison of one way slab v/s two way slab is based on ratio of longer span length to the shorter span length of the slab.

What is One Way Slab?

If the ratio of loner span to shorter span is more than two, say slab is resembling like a rectangle then it is called one way slab.
Properties of One Way Slab

  1. We need to provide main steel along shorter span and distribution steel along longer span in the one way slab.
  2. The two longer opposite sides are supporting most of the load of slab.
  3. The deflected shape of a one way slab is cylindrical.
  4. The bending occurs in one way slab in only shorter span.

What is Two Way Slab?

If the ratio of longer span of the slab to the shorter span is less than of equal to two then it is called two way slab.
Properties of Two Way Slab

  1. This slab transfers its load on all the four supporting beams.
  2. We need to provide main steel in both the direction of slab.
  3. The deflected shape a two way slab is saucer like.
  4. The bending occurs in two way slab in both the direction.
